ABSTRACT:
An impeller for a pump, especially a vortex pump, provided with one or more straight or curved vanes arranged radially. Vortex pumps are used e.g. for pumping sewage, for which purpose they are well adapted. However, a drawback with such pumps known so far has been a rather low efficiency and a low lift curve. In the vortex pump of the invention, this problem is eliminated by providing the edges of the vanes with flanges essentially perpendicular to the vane surface.
